SMOKE AND GAS CONSUMER.

SPECIFICATION forming part of Letters Patent No. 594,267, dated November 23, 1897.

Application m May 26,1897. Seria1No.-638,240. on model.)

gines, and arranged to insure a complete combustion of the burning fuel.

The invention consists principally of an open pipe-frame arranged in the top of the fire-box, along the sides and ends thereof, directly below the crown-sheet, the said frame being connected with an air-su pply, each pipe thereof being formed with a-longitudinal slit opening inwardly to discharge air upon the flame of the burning fuel.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claim.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a transverse section on the line 1 1 of Fig. 2 of the improvement as applied to a locomotive-boiler. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1.' Fig. 3 is a cross-section taken upon the line 3 3 of Fig. 1, and Fig. 4 is a cross-section taken upon the line 4 4 of Fig. 1.

My device is shown in the drawings as applied to a boiler of the locomotive type. It may, however, be applied to boilers of any type. As there shown, it comprises a frame A, formed of pipes and extending about the It is preferof two sets of pipes, an inner set A containing air, and an outer set A forming with the inner an annular space which is to be used as a water-jacket. These pipes upon their in:

ner edges are provided with narrow slits A, through which the air is discharged into the fire-box.

As shown in Fig. 4, the space between the inner and the outer tubes on each side of the slits A is closed by the partition a, so that the air may be discharged from the inner pipe without permitting the escape of water from the water-jacket surrounding it.

At each corner of the frame A is placed a stand-pipe consisting of the inner air-conveying pipe D and the outer pipeD, forming a part of the water-jacket. The pipes D extend beneath the grate and are provided at their lower ends with a sieve or strainer G, adapted to prevent the entrance of ashes and cinders, which would have a tendency to clog the discharge-slit A if permitted to'enter the pipes.

The stand-pipes are connected to the interior of the boiler at top and bottom by connections Fand F, consisting of short sections of pipe which are joined by unions. This permits a free circulation of Water through the water-jackets, and thus protects the pipes against being burned out.

The frame A is supported from the crown of the fire-box by means of yokes 0, attached thereto and passing about the pipes of the frame.

Having thus. fully described my invention, I claim as new and desire to secure by Letters Patent- A furnace provided with a rectangular pipeframe supported in the fire-box, each pipe in the said frame having a longitudinal slit opening toward the center of the fire-box, standpipes one at each corner of the frame with their lower ends opening in the ash-pit and their upper ends communicating with the pipes of the frame, and said pipes each having a surrounding water-jacket, substantially as described.
